Answer:
Square root ( 2 )
Step-by-step explanation:
We have to determine which value is equivalent to | f ( i ) | if the function is: f ( x ) = 1 - x. We know that for the complex number: z = a + b i , the absolute value is: | z | = sqrt( a^2 + b^2 ). In this case: | f ( i )| = | 1 - i |. So: a = 1, b = - 1. | f ( i ) | = sqrt ( 1^2 + ( - 1 )^2) = sqrt ( 1 + 1 ) = sqrt ( 2 ).
We use a conjecture that says that the perpendicular bisector of a chord in a circle passes through the center of the circle.
The distances of the two bisectors are the same so the chord lengths are the same.
b = half of 22.5 = 11.25
The answer to your question is 11.25.
